“Background: Malaria rapid diagnostic tests (RDTs) are now widely used for prompt on-site diagnosis in remote endemic areas where reliable microscopy is absent. Aberrant results, whereby negative test results occur at high parasite densities, have been variously reported for over a decade and have led to questions regarding the reliability of the tests in clinical use.
Methods: In the first trial, serial dilutions
of recombinant HRP2 antigen were tested on an HRP2-detectiing RDT. In a second trial, serial dilutions of culture-derived Plasmodium falciparum parasites were MI-503 manufacturer tested against three HRP2detecting RDTs.
Results: A prozone-like effect occurred in RDTs at a high concentration of the target antigen, histidine-rich protein-2 (above 15,000 ng/ml), a level that corresponds to more than 312000 parasites per mu L. Similar results were noted on three RDT products using dilutions of cultured parasites up to a parasite density of 25%. While reduced line intensity was observed, no false negative results occurred.
Conclusions: These results suggest that false-negative malaria RDT
results will rarely occur due to a prozone-like effect in high-density infections, and other causes are more likely. However, RDT line intensity is poorly indicative of parasite density in high-density infections and RDTs should, therefore, not be considered quantitative. Immediate management of suspected severe malaria should rely on clinical assessment or microscopy. Evaluation against high concentrations of antigen should be considered in malaria RDT product development and lot-release testing, to https://www.sellecn.cn/products/byl719.html ensure that very
weak or false negative results will not occur at antigen concentrations that might be seen clinically.”
“A novel technique based on microwave irradiation was developed to synthesize polyhydrazide and polythiohydrazide. These polymers were readily synthesized by the reaction of aromatic and aliphatic dihydrazides with urea and thiourea. The effects of microwave irradiation time, power, solvent nature, and solid content of monomers on the inherent viscosity of the polymers were investigated. The polymers were characterized by 1H-NMR and IR spectroscopy and elemental analysis. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012″
